SPECIFICATION 'forming part of Letters Patent N0..278,0l22, dated May 22, 1883. Appilcation filed February 8,1883. (No model.)

To all whom it may concern I Be it known that I, LEWIS 'T. KLINE, of' Alpena, in the county of Alpena and State of Michigan, have invented new and useful I mprovements in Log-Rollers; and I hereby declare that the following is a. full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

The nature of this invention relates to certain new and useful improvements in the construction of devices for loading or rolling logs fromskids in a saw-mill to the circular-saw carriage; and the invention consists in -the peculiar construction of arms keyed upon a rock-shaft, and in the means employed for operating the same, all as more fully hereinafter.

Figure 1 is a side elevation of my improved device as in the act of rolling a log from the skid to the carriage. Fig.2 is a similar view with the parts in the reversed position. Fig;

In the accompanying drawings, which form a part of this specification, A represents the skid-timbers, which are supported upon the the saw-carriage is placed, such skids gradually inclining toward the carriage (J.

D represents a'shaft, which is journaled in proper bearings across the skids and near the front end thereof, and uponeach or near each end of this shaft is rigidly secured the casting which carries the arms E, F, and G. These arms are preferably cast 'with and form an in- H represents a steam-cylinder, which is rigidly bolted or otherwise secured to the side of the skid-timbers, the piston'rod H of such cylinders being properly securedto the arm G; or such connection may be made through This cylinder is provided with a proper valve,

the stem of which is connected by a system of compound levers, I, which in turn are connectany proper source of supply to thecylinder, and to cause the piston to advance or retract, as-

mitted into the cylinder upon the front face of the piston-head, which causes such piston to travel toward the rear end of its cylinder, and by the connections herein named neces sarily draws the three levers into the position shown in Fig. 1, wherein the arm E has been lowered to or about the same level withthe skids, while the lever F coines up in behind v the log and starts it forward, rolling it upon the carriage down the inelinc' of the skid, while at the same time this lever F acts as a block and prevents the other logs from movingforward. Wheait is desired to allow another log to advance the lever is then thrown in the opposite direction, which compels the three arms to assume the position shown in Fig. 2, and the operation above described is repeated as often as it is desired to supply the saw-carriage with a. fresh log.

What I claim as my invention is- 1. In a device for rolling logs from a skid. to asaw carriage, a series of rocking arms mounted on a horizontal shaft suitably jo'urualed in v said skids, an engine-cylinder having its'piston-rod suitably connected to the lower one of said roekin g arms, and controlling mechanism,

substantially as described."

2. In a device'for rolling'logs, one or more series of. rocking arms, the rear one of which is raised by the depression of the remainder of theseries and forms a stop against the stat-ionary logs, andbetweeu which arms the 'moved log is carried, a horizontal shaft upon which all the rocking arms are mounted; a suitable frame orskid, and means for partially rotating andthen reversing the shaft and arms, substantially asset, forth.

3. In combinationwihthe skids A,- shaft D, and one or more seriesof "rocking arms, E F G, suitable actuating-power cylinder, H, rod H, conuectedtoarm Gmnd suitable'valveas shown and described. 1 LEWIS T. KLINE Witnesses; Joanqconroagr, F. H. VRooMAN.
